4. For the PPC devices we use this pin to supple power to the buffer chip in the JTAG Cable. The series resistor must be bridged. Bridge R67 on the Kuro, Kuro HG, LS1, and LS-HG. Bridge R370 on the Terastation. This should result in a voltage of approximatley 3.3v being present on these pins. On the LS-HS it is easiest to take the 3.3v from Pin 3 of the Serial Port connector.
